Specification of Lettera Patent. Patented Allg. 26, 1919.

Application tiled Iune 16, 1916. Serial No. 104,047.

To all 'whom it may concern.'

Be it known thatl MAnvlN SMrrHnr,V a citizen of the United States, and a resident of Lawrenceville, in the county of Brunswick and State of Virginia, have invented a certain new and useful Improvement in Meters, of which the followingis a speciiication.

My invention relates to improvements in meters, and it consists inthe combinations, constructions, and arrangements herein de scribed and claimed.

An object of my invention is to provide a novel form of meter to be used with an automobile or other similar vehicle for the purpose of keeping track of the mileage of tires or other similar parts of the vehicle, there being an odometer or registering device for each of these individual features.

A further object of my invention is to provide a meter which is capable of having any one of' its several odometers released' from the driving mechanism and reset at will.

A'urther ob'ect of my linvention is provide a plura ity of odometers driven s1- multaneously and a movable device for en-y gaging each ofthe odometers to throwY the atter out of operative position and also to reset it.

A further object Aof my invention is to provide a novel form of speedometer, which maybe used in connection with the odometers.

Other objects and advantages will appear in the following specification, and the novel features of the invention will 4bepartcnlarly pointed out in the a pended claims.

1 My invention is i lustrated in the accompanying drawings forming part of this .1pp1ication,-in which- Figure 1 is a face view of the meter.

Fig. 2 is a horizontal section along the line 2-2 of Fig. 7.

F'g. 3 is a section along the line 3 3 of Fig. 2.

Fig. 4 is a section on the line 4--4 of Fig. 5.

Fig. 5 is a section on the line 5-5 of Fig. 1.

Fig. 6 is a detailed sectional view of one of the odometers.

Fig. 7 is a side view partially broken awa of the meter.

Fig. 8 is aftop plan view of a modified form of meter with the settingr ring removed.

; Fig. 9 is a bottom plan view of the setting ring' Fig. 10 is a detailed section on line 10-10 of Fig. 4. Fig. 11 is a perspective viewof the centrifugal actuating deviceV for they speedometer.

In carryin casing l whic is c lindrical in shape. Disposed at the rear ci the casing is a centrifugal device consisting of a Shaft 2 which is mounted to rotate in bearings 3. Disposed at substantially the center of the shaft is a centrifugal wheel 4. As will beseen from Fig. 2, this wheel is pivotally mounted at l", so that it may turn from the dotted line p osition shown in Fig. 2 to thev full line positlon or vice versa.

The shaft 2 is provided with an enlarged portion, 2". Surrounding the shaft 2 on one side of the portion 2t is a spiral spring 5, which bears at one end on a slidable collar 6, the other end bearing on the portion 2*. On

lar spring 7, which bears at one end of the portion 2*, and on the opposite end on a slidable collar 8. I desire to call particular attention to the construction of these springs. It will be observed that. they are made heavy in the central portion and lighter toward their ends. I

The wheel 4 is connected with the slidahle collar 6 by means of a link 9, which is pivtall);r connected to the wheel at 9 in a slot. 9V. The slidable collar 8 is connected to the opposite side of the wheel by a link 10, which is pivotally secured at l0l in a slot 10V.

The collar 6 is`p1ovided with agroove 11 arra ed receive the spherical end 12* of a pivo ed arm 12. The opposite end of `this arm 1s formed'in the shape of a segmental gear 13, which meshes with a pinionli on a shaft 15. The shaft 1", as will be seen from Fig. 1, bears an arm or pointer 16, which lays over a dial 12' indicating miles per our.

The s cedometer arrangement thus far describe operates.r in the following manner. Normally, when the vehicle is at rest, the

position of the parts is that shown in Fig. 2..- When the shaft 2 is turned by means of flexr out myinwen'tion I provide a so, like that Shown in ig.

wheel 4 tends to also move the collars 6 and 8, and therefore to compress these s rings.

making the springs larger an heavier B v in the center, the movement of the collar 6 of the collar 6 will be in exact proportion to the speed of the vehicle.

The means for. measuring the mileages vilrlhich are obtained by the various parts of t e f shaft' 2, at the end of which is a bevel gear 19, see Figs. 11 and 5. This meshes with a gear 20, on a shaft 21, bearing a gear 22, see Fig. 4, which is in mesh with a gear 23, that engages a gear 24 on a shaft 25, having a gear 26, engaging a pinion 27 on a sleeve 28. The latter bears a gear 29 enga ing a. pinion 30 on a shaft 31, upon whic is a. gear 32 meshing with a. ar 33 on a shaft 34. This shaft extends t rough a partition 35, and bears at'its end, a bevel gear 36. This bevel gear 36 is in mesh with two bevel rs 37 land 37', respectively, the former ing on a common shaft with a bevel gear 39, which meshes witha bevel gear 40 on a shaft 41. The latter shaft bears worins 42 arranged to mesh with worm wheels 43, one of which is carried by each odometer 44. That portion of the apparatus includingthe members 20 to 33, inclusive, constitute a gear train for reducing the speed. The parts including those from 37,5044 are duplicated on the opposite side of the bevel gear 36, the members 37 to 44` inclusive corrponding to the parts having the'same numerals on the o osito' sides.

As wil be observed from Fig. 6, each of the odometers is rovided with a shaft like that shown at 45 in Fig. 6. This shaft bears a bevel ar 46. Each odometer is pivotally mountede at 47 and is held by a spring 48 in such position that iits worm wheel 43 or 43 as the case may be, will be normally in gement with its worm 42 or 42. s will be seen from Fi 4, the shafts 45 of the odometers project t rough the casing 1./ The upper partof the casing 1 is rovided with an inwardly extending annuiiir flange 1*, which sup rts a setting ring 9. This setting rin bears a thumb wheel '51 on a shaft 52, which is journaled in a sleeve 53, see Fig. 5, carried 'by the ring 5, a spring 54 ten ing to liold the thumb wheel 51 normally in an upper position shown in dotted lines in Fig. 5. The opposite end of the shaft 5 2 is provided with a bevel gear 55, which is ehicle such as the tires, includes the arranged to engage an of the bevel gears 46, carried by the sha s 45 of the various Odoulieters.

In order to permit the gear 55 to be moved in the position, the flange l1t is slotted, as shown at l'. 'I he ring 50`rotates on the flange 1 as a bearing, and carries with it the shaft 52.

Secured to the flange 1 is a plate 57 which beais legends 58, such as extra tire No. 1, extra tire 2, and a reading opening 59 through which the odometers may lbe observe AA glass plate 60 is also carried by the plate 5 .From the fore foing description of the various parts of lie meter inerhanism, the operation thereof may be readily under- Normally, the odometers are all engaged by the driving mechanism, and are driven simultaneously. If now it is desired to rc'- cord the mileage of a newly replaced tire, the odometer corresponding to the tire is disengaged and reset by moving the thumb wheel 51 around miti it is opposite the odometer, then pressing inwardly to bring the bevel gear 55 into registration with the bevel gear 46, see Fig. 5. The inward movement 0f the gear 55 will cause the opposite end of the pivoted shaft 45 to lift the worm 43 away from the worm 42, thus disengagiiig the odometer from its drivin inei'hanism. Now, b` turning the whce 51, the wheel 45 may e turned, and thc wheels reset. It may here be stated that the specific construction of-the odometer Iforms no part of the pri-sent invention, and any form in which the turning of its shaft will reset the number wheels may be used. If it is desired to temporarily put the odometer out of operative relation with its driving mechanism, then the end of the shaft 45 may be Secured by means of u. hook, such as that shown at 61 in Fig. 7.

In Figs. 1 and 4 I have-shown a motor having six (6) odometers, while in Fig. 8 I have shown a modified form in willi-height (8) odometers arc used, otherwise the devices are identical.
